Description

Long stator linear motor

Technical Field

The invention relates to long stator linear motor, which has a transport path, along which at least transport carriages are arranged to be movable in a movement direction, comprising at least 0 holding structures with drive coils, on which holding structures passive components of the transport carriages are arranged, which have guide surfaces extending along the transport path and guide rails extending along the transport path, which passive components have at least -th drive magnets, which -th drive magnets are arranged parallel to the guide surfaces leaving an air gap, which transport carriages have at least -th -th profiled elements, which -th profiled elements are arranged on the guide rails and are positioned in a lifting direction extending perpendicular to the movement direction and the transverse direction by a pressing force acting on the guide rails in the transverse direction, and at least -th -th driving elements support the passive components on the holding structures against an attraction force acting between the drive magnets and the drive coils to ensure the air gap.

Background

Long stator linear motors of this type are known in the prior art, for example from US 9,428,347. The advantage of the profile arrangement provided in the guide rail is, in particular, that it is simple to use, since the transport carriage can be simply and tool-free added to and removed from the transport path again. However, the disadvantage is that the transport carriage can "derail" at too low a pressing force or at too high a load, i.e. the profile system falls out of the guide rail, whereby the transport carriage falls out of the holding structure. It is therefore not possible to equip the transport path with a bilaterally arranged drive coil, since this arrangement (also referred to as a double comb arrangement) does not achieve the required pressing force. However, a double-sided arrangement is required in particular in the area of the bifurcation, in particular if the bifurcation is to be operated without mechanical movement control elements.

Disclosure of Invention

The object of the invention is to provide long stator linear motors, the transport carriage of which can be added without tools by simply placing the transport carriage on the holding structure of the transport path and removed from the holding structure simply by lifting the transport carriage against the magnetic force, but which allow a double comb arrangement of the drive coils and the provision of the fork.

The aforementioned and other objects are achieved according to the invention by a transport path of the type mentioned at the outset, in which the transport carriage has at least st auxiliary guides, the st auxiliary guides cooperating with auxiliary guides arranged on the holding structure at least in the diverging and/or converging regions of the transport path to limit the movement of the transport carriage in the positive and/or negative lifting direction at least on the side , whereby the transport carriage can also travel over transport path regions in which the contact pressure of the profile means on the guide rail is insufficient to hold the transport carriage securely in the guide rail.

The term "guide rail" in connection with the present disclosure refers to a shape element extending along a transport path, which has a negative (i.e. concave) profile, a positive (i.e. convex) profile or a combination of negative and positive profile portions. The term "profile mechanism" refers to a counterpart which is arranged on the passive component, which is adapted to the guide rail and which is adapted to the guide rail, which can be configured in particular as a profile sliding element or as a profile roller. The profile mechanism and the guide rail are designed such that a component of the attractive force between the drive coil and the drive magnet, which component acts in the transverse direction (i.e. along the y-axis), is deflected into a force acting in the z-direction. The force acting in the z-direction may receive a component of the force of the weight of the vehicle and of the goods transported on the vehicle acting in the negative z-direction.

Advantageously, the auxiliary guide means may be spaced apart from the auxiliary guide means when the profile means is centred on or in the guide rail. The auxiliary guide thus does not generate disturbing friction in the area of the path where the contact pressure is sufficiently high.

In another advantageous embodiments, the auxiliary guide means can be arranged only in the diverging and/or converging region of the transport path, in particular the branching, which is adjustable without mechanically moving parts, is required for such diverging and/or converging region.

The combination of the profile means and the running gear simplifies the insertion of the carriage and ensures a defined distribution of the contact pressure.

In an advantageous embodiment, a second chassis arranged opposite the first chassis and/or a second guide arranged opposite the second auxiliary guide and/or a second profile arranged opposite the second profile and/or a second drive magnet arranged opposite the second drive magnet can be provided on the transport carriage, these features allow a bilaterally arranged holding structure to be produced, wherein the second holding structure can be designed passive (i.e. without a drive coil) or active (i.e. with a drive coil).

The term "retaining structure" in connection with the present disclosure generally refers to a unit of stationary parts of a long stator linear motor. The term therefore includes the active elements, in particular the drive coil (or stator) and its mountings, as well as all path guide elements on which the carriage slides or rolls along.

In a further advantageous embodiment, the and/or second profile means, the and/or second chassis and/or the and/or second auxiliary guide means can be designed independently of one another as rollers, sliding elements or as a combination of rollers and sliding elements.

The invention is based on the object of providing a combined sliding/rolling mechanism, in which at least profile means can be constructed with their axis of rotation centrally arranged in the passive part, which profile means project in the transverse direction on both sides from the passive part.

Alternatively, at least chassis elements can be designed as a combined sliding/rolling element, the axis of rotation of which is arranged centrally in the passive part, said chassis elements projecting laterally beyond the passive part on both sides.

The above features may be combined in any manner with the previously described features to design an advantageous long stator linear motor or transporter. The design of such combinations is within the ability of one of ordinary skill in the art.

The invention also relates to types of vehicles having the characteristics listed above for the vehicle.

The transport vehicle and the long stator linear motor are interrelated products which cooperate and complement each other.

Detailed Description

Fig. 1 shows exemplary transport applications of a long stator linear motor 1 with a transport path 2 along which a plurality of transport carriages Tn (n ≧ 1) can be moved, for the sake of simplicity only only transport carriages Tn are shown in fig. 1, in which application usually a number of transport carriages Tn, , typically several hundred, are moved simultaneously, the transport path 2 comprises drive coils Sm (m denotes an index from 1 to the number of drive coils) arranged alongside one another in the direction of movement x, which are arranged on a stationary holding structure 3 (only schematically shown in fig. 1), which drive coils Sm can be controlled by a device control unit 5 (only and only drive coils are schematically shown in fig. 1) in order to energize them in order to generate a moving magnetic field, drive magnets Sm 4 are arranged on both sides (viewed in the transverse direction y) of the transport carriages Tn, which interact in a known manner with the magnetic field generated by the drive coils Sm in order to move the transport carriages Tn., preferably only the drive coils Sm 4 in the energized drive regions of the drive coils Sm.

The cartesian coordinate systems x, y, z used are coordinate systems which are moved with the transport carriage Tn , where x always points in the direction of movement of the transport carriage Tn, which is essentially predetermined by the transport path 2.

The direction of movement in a curved section is of course a tangent to the curve. The direction of movement x can therefore in principle be oriented arbitrarily in space, depending on the design of the transport path 2. y denotes the transverse direction transverse to the direction of movement x and in the direction of the air gap 10 between the drive magnet 4 on the transport carriage Tn and the drive coil Sm on the transport path 2. z is perpendicular to the x and y axes of the transporter Tn and is referred to in connection with the present disclosure as the elevation direction z, which name should not be construed as limiting. Typically, but not necessarily, the plane of the air gap 10 is parallel to the x-z plane and the y-direction is perpendicular to the air gap plane.

The orientation of the axes of the coordinate system is of course not limited to that shown in the drawings, but is in principle arbitrary. For example, a long stator linear motor 1 can be realized in which the drive coil Sm and the drive magnet 4 are not arranged on the side, but are arranged above and/or below. Whereby e.g. the y-axis and the z-axis will interchange positions. Alternatively, the drive coil Sm and the drive magnets 4 can also be arranged in a plane extending obliquely to the x-z axis, wherein a V-shaped configuration can also be realized in a double comb arrangement, for example.

At least branches W are also provided on the transport path 2, which connect the segment 2a of the transport path 2 and the second segment 2b branching off from the segment, it being determined by changing the branches W whether the transport carriage Tn is moved further along the segment 2a or is diverted substantially in the transverse direction y onto the second segment 2b and is moved along the second segment 2b, the two segments merging into segments in the other movement direction, so that it can be moved generally in both movement directions through the branches W.

The transport path 2 does not necessarily have to be in planes, such as the x-y plane of fig. 1, but may also extend arbitrarily in space.

In order to also be able to use a route with a bilaterally arranged holding arrangement 3, vehicle guide elements 7 are provided on both sides of the transport carriage Tn (viewed in the direction of movement x) in the transverse direction y. The carriages Tn are advantageously constructed symmetrically with respect to the x-z plane for this purpose, as shown in fig. 2.

A path guide element 6 is arranged on the transport path 2, which cooperates with a vehicle guide element 7 on the transport carriage Tn, so that the guide of the transport carriage Tn. along the transport path 2 in the direction of movement x the path guide element 6 can be arranged on the holding structure 3 or on the part of the holding structure 3, but can also be arranged in other ways on the transport path 2.

The transport path 2 can be designed here on one side or on both sides (again viewed in the transverse direction y), as will be explained with reference to fig. 2. Fig. 2 and 3 show cross sections of the transport path 2 and of the transport carriages Tn, respectively, transverse to the direction of movement x (in the y-z plane).

In fig. 2a transport carriage Tn. arranged on the holding structure 3 is shown in a sectional view in the y-z plane, i.e. transversely to the direction of movement x fig. 2 shows a part of special designs of the path guide element 6 and the vehicle guide element 7. the path guide element 6 comprises the holding structure 3 and a drive coil Sm arranged in the holding structure, and the vehicle guide element 7 essentially comprises the passive part 13 of the transport carriage Tn together with the drive magnets 4 arranged thereon and the corresponding guide rollers and/or sliding elements.

The transport carriage Tn usually comprises passive components 13 which are assigned to the holding structure 3 and an upper structure 16 which is usually designed for the goods to be transported, the passive components 13 of the transport carriage Tn are supported on the guide surface 11 of the holding structure 3 by means of (at least) running gears 8 which are configured as wheels or rollers in the illustration of fig. 2 and (at least) profile gears 9 which are configured as profile rollers in the illustration of fig. 2, wherein the profile gears 9 are embedded in guide rails 12, the function of which will be described in more detail below, in an alternative embodiment the running gears 8 can be mounted on a running gear guide which is arranged separately from the guide surface 11, for example exclusively , and roll or slide on them, the guide rails 12 can also be configured separately from the guide surface, as an alternative, the guide rails 12 can also be configured as projections or as positive contours, the profile gears 9 in this case having matching negative contours, the transport carriage Tn is provided with drive magnets 4 in the region lying opposite the guide surface 11, on the guide surface 11 is provided with Sm., the disclosed means that the passive components 13 are assigned to the side regions Sm 9 of the transport carriage which are provided with drive magnets and the drive magnets 8, which are also act between the drive coils 8 and the drive mechanism Sm 4, which drive magnets 11, which are also act on the drive mechanism Sm 4, and which drive mechanism Sm 9, which is also acts between the drive coil surfaces 10.

The transport vehicles Tn can be added to or removed from the transport path on open road sections, i.e. road sections with only one-sided arrangement of the holding structures 3. For the addition, the transport carriage Tn is inserted with the profile mechanism 9 into the guide rail 12, wherein the carriage 8 is supported on the guide surface 11. The magnetic force between the drive coil Sm and the drive magnet 4 generates a significant contact pressure by which the carriage Tn is pressed firmly with the carriage 8 against the guide surface 11 and with the profile mechanism 9 into the guide rail 12. The profile means 9 is thereby centered in the guide rail 12 by the contact pressure and is guided into a position defined about the z-axis. At the same time, a force component oriented perpendicular to the pressing force direction, i.e., parallel to the z-axis, is generated by the pressing force, which force component is sufficient for accommodating the weight of the transport carriage Tn and thus the transported goods.

In the embodiment shown in fig. 2, the profile means 9 has a wedge-shaped profile, the guide rail 12 is configured as a groove with a corresponding V-shaped profile, the profile means 9 rests with its (in the illustration of fig. 2) lower profile side against the lower guide surface of the guide rail 12, on account of this inclined bearing and thus a normal force extending obliquely to the pressing force, a force component directed in the z direction is generated which pushes the transport carriage Tn upwards (in the illustration of fig. 2) until the profile means is centrally arranged in the middle of the guide rail 12, the force component generated thus depending on the pressing force and the inclination of the profile, which force component must be sufficient for accommodating the self weight of the transport carriage Tn and the weight of the goods transported by the transport carriage Tn, the vertical movement of the profile means 9 and thus of the transport carriage Tn is limited by the upper guide surface of the guide rail 12 (in fig. 2) in the other directions (i.e. upwards).

However, in addition to the V-shaped profiles shown, any other profile combinations of profile means profiles and guide profiles can be used, as long as they produce a centering or positioning effect and a corresponding force component on the basis of the pressing force. Since the attractive force acting between the drive magnet 4 and the drive coil Sm is usually very strong, relatively large loads can be transported in this way without the need for additional guiding means in the z-direction.

The guide can also function in any tilted position, i.e. when the force of gravity does not act in a negative direction of the z-axis. In practice the path guide may be arranged in a horizontal plane, but it may also have a slope (ascending and/or descending) or even a vertical section, and/or it may extend at least in sections obliquely, or even "upside down" (upside down in this case meaning that gravity acts in the positive direction of the z-axis).

The section of road provided with the holding structure 3 only on the side of the path (or of the passive component 13 of the transport vehicle Tn) is referred to in connection with the present disclosure as "single comb area".

However, it is often also desirable or necessary to provide a further holding structure 3 'on the opposite side of the passive component 13, as is indicated by the dashed lines in fig. 2, for which purpose the transport carriage Tn arranged between the holding structures 3, 3' is constructed essentially symmetrically, wherein sets of corresponding chassis 8, 8 'and profile means 9, 9' are provided on both sides, respectively, optionally the transport carriage Tn can also be constructed asymmetrically in relation to the passive component 13 and/or the superstructure 16.

The section of road provided with retaining structures 3, 3' on both sides (for example the section of road 2c or the bifurcation area shown in fig. 1) is referred to in connection with the disclosure as "double comb area".

Since the opposite drive coils Sm, Sm 'are arranged on both sides of the passive component 13 in the double comb region and act in opposite directions on the drive magnets 4, 4' of the transport carriage Tn, the transverse forces generated (i.e. the forces acting in the transverse direction y) are substantially zero, so that no profile mechanism 9, 9 'is pressed into or onto the respective guide rail 12, 12'. But the transport carriages Tn cannot fall out of the holding structure 3 due to the double-sided guidance in the opposite guide rails 12, 12'.

However, problems with the double comb arrangement can occur in the diverging or converging region, i.e. the holding structures 3, 3' on both sides diverge or converge towards one another, for example at a bifurcation. The attractive forces between the drive coils Sm arranged on both sides and the respective drive magnets 4 act from both sides on the passive component 13, so that the resulting contact force pressing the chassis 8 or the profile arrangement 9 against the guide surface 11 (or into the guide rail 12) is lost. However, since the two holding structures 3, 3' are already too far apart from one another, they can no longer play a "clamping" holding role. This can lead to the transport vehicles Tn falling out of the guide in the divergence or convergence region, which then disturbs the transport path 2. This problem is exacerbated especially when the transport load is high. Higher transport speeds may also exacerbate the problem based on greater centrifugal forces in the curved route. This effect is independent of the control, since it also occurs in the non-energized condition and involves only the attractive force between the drive magnet 4 and the stator core.

In order to avoid this interference, the transport carriage Tn has at least additional auxiliary guide devices 14 according to the invention, which limit the movement of the transport carriage Tn in the lifting direction z.

The auxiliary guide 14 can be designed, for example, as a roller, a slide or a combined roller-slide mechanism, which slides or rolls at least temporarily on the auxiliary guide 15, which is designed, for example, as a guide surface, of the holding structure 3 and limits the movement of the transport carriage Tn in the (positive and/or negative) lifting direction z, the auxiliary guide 15 can be arranged only in the diverging or converging region of the transport path 2 or it can be arranged on the holding structure 3, 3' along the entire transport path 2, the transport carriage Tn can be provided with auxiliary guides 14 of only , which act, for example, only on the side of the transport path 2, or the transport carriage can have a plurality of auxiliary guides 14, which can optionally be arranged on both sides.

In fig. 2, two guide rollers are provided as auxiliary guides 14, 14', which are each arranged on the side of the transport carriage Tn, the rolling surfaces being oriented towards an auxiliary surface 15 arranged on the holding structure 3, the orientation of the auxiliary surface 15 in the x-y plane, i.e. parallel to the direction of movement x and the transverse direction y., in the very simple assumption shown in fig. 2, the auxiliary surface 15 is oriented perpendicular to the guide surface 11, but this is not a necessary prerequisite, and the auxiliary surface 15 can also be oriented at an angle towards the guide surface 11, for example .

In the position of the transport carriage Tn which is guided as intended, i.e. when the profile means 9 (or the profile means 9, 9') are arranged in the guide rail 12 with a precise fit, the auxiliary guide means 14 preferably do not contact the auxiliary guide 15, but the auxiliary guide means 14 only contact the auxiliary guide 15 when the profile means 9 has somewhat "fallen out of the guide rail", as is schematically shown in connection with fig. 3 and 4. The representation of fig. 3 and 4 corresponds in design terms substantially to the embodiment of the transport carriage Tn and the holding structure 3 shown in fig. 2, only relevant parts of which are shown here.

Fig. 3 shows a substantially centered position of the profile means 9 in the guide rail, i.e. an offset b of zero or (as shown) negligible, i.e. within a functionally predetermined tolerance range. In this position the auxiliary guide 14 is spaced from the auxiliary guide 15 and "floats" above the surface of the auxiliary guide 15 in a non-contact manner, so that friction effects are avoided.

For example, in the divergent or convergent region of the holding structure 3, 3', the profile means 9 can be moved out of the centered position, for example, on the basis of gravity, as is shown in fig. 4 by a relatively large offset b. In this case, the auxiliary guide means 14 comes into contact with the auxiliary guide 15 and thus prevents the profile means 9 from sliding further out of the guide rail 12.

The displays of fig. 3 and 4 are distorted for clarity and are not shown to scale. Typically, the maximum distance a is very small, for example in the range of millimeters or less. Thereby ensuring that the width s of the air gap 10 is not too large. Based on the inclined profile of the guide rail 12 or the profile means 9, the width s of the air gap 10 between the drive coil Sm and the drive magnet 4 varies with the offset b, not only between the auxiliary guide means 14 and the auxiliary guide 15, but also between the guide surface 11 and the surface of the passive component 13 and thus also between the drive coil Sm and the drive magnet 4. In order to optimize the magnetic action, it is advantageous that the width s of the air gap 10 is kept as small as possible.

In practice, this can be achieved by providing a further auxiliary guide on the transport carriage Tn, which further auxiliary guide is in contact with a second auxiliary guide, which second auxiliary guide is arranged on the holding structure 3 opposite the auxiliary guide 15 in the lifting direction z.

In a further alternative embodiments, the holding structure 3 and the auxiliary guide means 14 can be designed such that they are in contact by default and the profile means 9 are thus substantially forced to be centered or positioned in the guide rail 12 in a further embodiment, the auxiliary guide means 15 can be provided only in the diverging or converging regions of the bifurcation or transport path, for example by providing the holding structure 3 in these regions with a raised surface or track region, with which the auxiliary guide means 14 can be in contact there.

Many other advantageous implementation variants are conceivable in relation to the design of the passive components 13 of the transport vehicle Tn. For example, instead of the rollers and wheels described above, sliding elements can also be used for the chassis 8 and/or the profile means 9. The mechanical complexity and thus the weight of the passive components 13 can be significantly reduced.

In a further variants, profiled elements 9 and/or chassis 8 can be designed as combined sliding/rolling elements, the rotational axes of which are arranged centrally (i.e. parallel to the z-axis in the x-z plane) in the passive part 13 and the contours or rolling surfaces project on both sides from the passive part 13, the profiled elements 9 and the chassis 8 rolling here in the single comb region, in which the rollers are pressed firmly by magnetic force on the guide surfaces 11 or in the guide rails 12, the elements thus acting as rollers, whereas in the double comb region, in which the pressing forces on both sides are minimal and the same rollers are arranged on each side in guide rails 12, acting as sliding elements on both sides, this embodiment makes it possible to achieve a very thin design of the passive part 13, which can be designed, for example, as a simple plate shape, and also to simply connect individual transport carriages arranged one behind the other in an articulated manner, so that they form a "train structure", which thus moves jointly as transport units.

In accordance with the embodiment of the transport carriage Tn, the holding structure 3 can have guide rails 12, respectively, the guide rails 12 can be arranged symmetrically or asymmetrically, i.e. the guide rails 12 can be constructed identically or differently on both sides, the advantage of the asymmetric arrangement being that the orientation of the transport carriage Tn is defined univocally, while the advantage of the symmetric arrangement being that the transport carriage Tn of the symmetric configuration can be placed on the holding structure 3 on both sides without the operator having to pay attention to the orientation.

Fig. 5 shows a transport carriage Tn according to another exemplary embodiments, which is arranged on the long-stator linear motor 1.

The passive components 13 of the transport cart Tn shown in fig. 5 are configured as relatively elongated plate-like bodies. The profile means 9 and the running gear 8 are designed as a combined sliding/rolling mechanism, the axis of rotation of which is arranged centrally (i.e. parallel to the z-axis in the x-z plane) in the passive component 13, the profile of the profile means 9 and the rolling surface of the running gear 8 respectively protruding on both sides over the passive component 13. The profile means 9 and the chassis 8 are arranged here in slots or channels which cross the passive component 13 in the transverse direction. A permanent magnet is provided as the drive magnet 4 on the side surface of the passive component 13 having a plate-like structure.

The auxiliary guides 14 are again configured as rolling bodies with axes of rotation parallel to the transverse axis, in which case only auxiliary guides 14 are provided in the respective receptacles on the lower end of the passive component (fig. 5). in the "normal" position (i.e. when the profile means 9 are centered in the guide rail 12), the auxiliary guides 14 can be spaced apart from the auxiliary guides 15, or the auxiliary guides can be in substantially continuous contact with this auxiliary guides 15.

Contrary to the embodiment of fig. 2, the holding structure 3 is in this case composed of a plurality of separate units, which are denoted by

reference numerals

3a, 3b and 3 c. The guide rail 12 is arranged in the guide rail 3b and the running gear 8 rolls or slides along the guide surface 3 c. The auxiliary guide 15 is also constructed as a separate unit. The part of the holding structure 3 denoted by reference numeral 3a contains only the drive coil and is otherwise not in direct mechanical contact with the transport carriage. This design facilitates maintenance and replacement of worn or damaged components.

The holding

structures

3a, 3b, 3c can also be arranged on one or both sides.
